Title:
  Use the kernel default for crashkernel offset

Status in The Ubuntu-power-systems project:
  In Progress
Status in makedumpfile package in Ubuntu:
  In Progress

Bug description:
  == Comment: #0 - Hari Krishna Bathini <hbath...@in.ibm.com> - 2018-01-08 
01:06:41 ==
  ---Problem Description---
  A default offset of 128MB is enforced for crashkernel by kdump-tools utility
  overriding the kernel default.

  While the kernel default offset for crashkernel is also 128MB, that may change
  and the right thing to do would be to let the kernel decide on the offset of
  crashkernel in the default scenario.. 

  Get rid of "@128M" in kdump-tools.cfg file

  ---uname output---
  na
   
  Machine Type = na 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
   # cat /etc/default/grub.d/kdump-tools.cfg 
  GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT 
crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M@128M"
  ---

  The offset is specified via kdump-tools where as the kernel may be the right 
place to
  set an offset by default..

   
  Userspace tool common name: kdump-tools 
   
  The userspace tool has the following bit modes: 64-bit 

  Userspace rpm: kdump-tools
